A Gyroscope is a fascinating mechanical device that at time seems to defy the laws of gravity. The unique characteristic of a gyroscope is that once it is set spinning, it tends to want to remain in its original plane regardless of rotation of its housing. The tendency to resist change in direction is the foundation of apparatuses that use gyroscopes. This fun and educational demonstration will teach you why this is true. This is a well balanced, high quality gyroscope with adjustable bearings. The unit includes a plastic gimbals, rocker and pivoting housing, the gyroscope and cord.
